User can get only one additional license for free – so users who always have additional license can’t get second additional license.
You will get only one license for free, regardless of the number of licenses purchased.
Of course all customers who already have a license (but haven’t additional license) also can take advantage of this offer. Simple buy one or more licenses during the term of this offer.
The additional license will be canceled in case if customer use the refund or combines 2 or more 3d-kstudio accounts into one.

Hi Alex,
I’d be interested in that too. My understanding is that if I buy one or more license of project manager I get one extra license for free.
I’m confused by “Of course all customers who already have a Project Manager license (but haven’t additional license) also can take advantage of this offer.”. I already have a bunch of licenses for my team, how does that apply to these existing license?
